1.1 Status of Automatic Appearance Inspection at FUJITSU TEN At manufacturing sites of FUJITSU TEN, to improve the external appearance of our products intended for the customers and to ensure the visual quality of our products, various inspections are performed. Conventionally, a visual inspection had been performed by inspectors. However, recently, to ensure the stability of the inspection qua...

Shearography has been validated as fast and reliable inspection technique for aerospace components. Following several years phase of evaluation of the technique, meanwhile, shearography has entered the industrial production inspection. The applications basically range from serial inspection in the production line to field inspection in assembly and to applications in the maintenance and repair ...

We examine the use of viewer-centred representations (VCRs) for object recognition, location and inspection, employed in the framework of advanced inspection systems. We introduce a recognitionoriented VCR of 3D objects and show how to compute it using cluster analysis of approximate visibility spaces. Using the same representational framework, we illustrate the automatic generation of VCRs for...

In this paper we propose a prototype for image sequence acquisition of glass wine bottlenecks, whose main novelty is the use of an inner lighting source for better capturing of potential defects. A novel approach for automatic inspection of the bottlenecks based on tracking potential flaws along the acquired sequence is also presented. Our inspection system achieves performance rates of 87% tru...
